Sometimes super light is not necessarily a good thing. It depends on the plane.
I have a QQ 85" Yak with a DA-50. If the BME 55 is lighter, the plane would practically never balance without adding lead.
Yep, he said a GP 27% cap.
Each plane is different. Are are you sure it would not balance with pull pull on the elevator or 1 elevator servo on long rods mid ship and a canister muffler on the motor? Maybe a little lead up front or heavy spinner?
